Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of water conservancy engineering technology, specifically a device for preventing steel wire rope derailment of a double-lifting-point gate. Background Technology
[0002] Double-point gates belong to the field of water conservancy and hydropower engineering technology, mainly used to control water flow and water level. In water conservancy projects, double-point gates can be used to control water level and regulate water storage, ensuring the safe operation of reservoirs and the rational allocation of water resources. In irrigation channels, the water flow rate and volume are controlled by adjusting the gate opening to achieve precise irrigation. However, in actual operation, existing double-point gates lack an effective full-range limiting mechanism for the gate's wire rope, relying solely on the winch's own rope groove for constraint. When vibration or uneven stress occurs during gate raising and lowering, the wire rope is prone to lateral deviation, easily slipping out of the winch's rope groove, causing the gate to malfunction and affecting the continuity of water conservancy operations. Utility Model Content
[0003] To achieve the above objectives, this utility model employs the following technical solution: A double-suspension-point gate anti-derailment device for wire rope includes a gate and a mounting base. The gate is slidably installed inside the mounting base. A motor and a reducer are fixedly installed on the top of the mounting base. The motor and the reducer are connected in a transmission connection. A transmission shaft is fixedly installed at the output end of the reducer. Winches are symmetrically fixed at both ends of the transmission shaft. A wire rope is wound on the winches. The other end of the wire rope is fixedly connected to the gate. A driven shaft is rotatably connected to the top of the mounting base. Wire rope retainers are symmetrically installed on the driven shaft. The wire rope retainers are sleeved on the outer ring of the wire rope.
[0004] The mounting base is symmetrically and fixedly provided with a first support base, and a first bearing seat is fixedly provided with a first bearing seat on the top of the first support base. The two ends of the transmission shaft are fixedly connected to the inner ring of the first bearing seat, and a drive gear is fixedly provided on the outer ring of the transmission shaft near the end.
[0005] The mounting base is symmetrically fixed with a second support base on top, and a second bearing seat is fixedly fixed with top of the second support base. The two ends of the driven shaft are fixedly connected to the inner ring of the second bearing seat. A driven gear is fixedly installed near the end of the outer ring of the driven shaft. The driven gear meshes with the driving gear. The outer ring of the driven shaft has two sets of double-threaded threads.
[0006] The mounting base is symmetrically fixed with support frames on the top, and slide rails are fixedly fixed on the top of the support frames. The bottom of the wire rope fixer is provided with a slide groove, which is slidably connected to the corresponding slide rail. Limiting frames are fixedly and alternately on the upper and lower sides of the wire rope fixer. Through holes are provided on the limiting frames, and the through holes are fitted onto the outer ring of the corresponding wire rope.
[0007] A gate frame is fixedly installed at the bottom of the mounting base. The two sides of the gate are slidably connected to the gate frame. Connecting rods are symmetrically fixedly installed at the top of the gate. The steel wire rope is fixedly connected to both ends of the connecting rods. The connecting rods pass through the mounting base.
[0008] Compared with the existing technology, the beneficial effects of this utility model are: This utility model has a simple structure and is easy to install and use. Through the meshing transmission of the driving gear and the driven gear, the driven shaft is driven to rotate, which in turn drives the wire rope fixing device to slide synchronously along the slide rail with the rhythm of wire rope winding and unwinding. With the limit frame set up vertically and vertically on the wire rope fixing device, the wire rope is constrained, effectively resisting the interference of vibration and uneven force during the gate lifting and lowering process, significantly reducing the risk of wire rope derailment, and ensuring the stability and safety of the gate opening and closing process. The device adopts a double-lifting-point structure with winches symmetrically set at both ends of the drive shaft. Combined with two sets of double-threaded wire ropes on the driven shaft and symmetrically arranged wire rope fixing devices, it ensures that the winding and unwinding speed and limiting force of the wire ropes on both sides are completely synchronized. This effectively avoids the derailment risk caused by asynchronous limiting and unbalanced force on both sides in the existing technology. At the same time, it ensures uniform force during the lifting and lowering of the gate, reduces problems such as gate tilting and jamming, and extends the service life of the gate and transmission components. The device achieves smooth power transmission and precise speed control through a multi-stage transmission structure consisting of a motor, reducer, and drive shaft. At the same time, the linkage anti-detachment mechanism moves synchronously with the transmission system, requiring no additional power drive, simplifying the control logic and reducing equipment energy consumption and failure probability.

[0011] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0012] Referring to the accompanying drawings, a double-suspension-point gate anti-derailment device for wire rope includes a gate 1 and a mounting base 2. The gate 1 is slidably installed inside the mounting base 2. A motor 3 and a reducer 4 are fixedly installed on the top of the mounting base 2. The motor 3 and the reducer 4 are connected in a transmission connection. A transmission shaft 5 is fixedly installed at the output end of the reducer 4. Winches 6 are symmetrically fixed at both ends of the transmission shaft 5. A wire rope 7 is wound on the winches 6. The other end of the wire rope 7 is fixedly connected to the gate 1. A driven shaft 8 is rotatably connected to the top of the mounting base 2. Wire rope retainers 9 are symmetrically installed on the driven shaft 8. The wire rope retainers 9 are sleeved on the outer ring of the wire rope 7.
[0013] The mounting base 2 is symmetrically fixedly provided with a first support base 10, and a first bearing seat is fixedly provided on the top of the first support base 10. The two ends of the transmission shaft 5 are fixedly connected to the inner ring of the first bearing seat, and a drive gear 11 is fixedly provided on the outer ring of the transmission shaft 5 near the end.
[0014] The mounting base 2 is symmetrically fixed with a second support base 12 on its top. The second support base 12 is fixed with a second bearing seat on its top. The two ends of the driven shaft 8 are fixedly connected to the inner ring of the second bearing seat. The driven gear 13 is fixedly installed near the end of the outer ring of the driven shaft 8. The driven gear 13 meshes with the driving gear 11. This structure drives the driven shaft 8 to rotate. The outer ring of the driven shaft 8 has two sets of double-threaded threads. Each set of double-threaded threads has opposite directions and equal pitch. This structure drives the wire rope fixing device 9 to reciprocate.
[0015] The mounting base 2 is symmetrically fixed with support frames 14 on its top. The support frames 14 are fixed with slide rails on their top. The wire rope fixer 9 has a sliding groove at its bottom, which is slidably connected to the corresponding slide rail. The upper and lower sides of the wire rope fixer 9 are alternately fixed with limiting frames 15. The limiting frames 15 have through holes, which are fitted onto the outer ring of the corresponding wire rope 7. This structural design prevents the wire rope 7 from derailing.
[0016] The bottom of the mounting base 2 is fixedly provided with a gate frame, the two sides of the gate 1 are slidably connected to the gate frame, the top of the gate 1 is symmetrically fixedly provided with connecting rods 16, the steel wire rope 7 is fixedly connected to both ends of the connecting rods 16, and the connecting rods 16 pass through the mounting base 2.
[0017] When in use, this device opens or closes according to the gate lifting and lowering requirements. The control system sends corresponding operating commands to the motor 3. After the motor 3 starts, the power is reduced and increased in torque by the reducer 4 and then transmitted to the transmission shaft 5, driving the transmission shaft 5 to rotate at a constant speed. Since the winches 6 are symmetrically fixed at both ends of the transmission shaft 5, the two winches 6 rotate synchronously with the transmission shaft 5, realizing the synchronous winding or release of the two wire ropes 7. At the same time as the transmission shaft 5 rotates, the drive gear 11 near the end of its outer ring rotates synchronously. Through gear meshing, it drives the driven gear 13 on the driven shaft 8 to rotate, thereby driving the driven shaft 8 to rotate as a whole. Since the outer ring of the driven shaft 8 has two sets of double-threaded threads, and the wire rope fixing device is matched with the threaded structure of the driven shaft 8, and the bottom of the wire rope fixing device 9 is slidably connected to the slide rail of the support frame 14 through the slide groove, the rotational freedom of the wire rope fixing device 9 is restricted. Therefore, the rotation of the driven shaft 8 will be converted into the horizontal reciprocating sliding of the wire rope fixing device 9 along the slide rail. During the winding or unwinding process of the wire rope 7 with the winch 6, the wire rope retainer 9 is always fitted around the outer ring of the wire rope 7 and slides synchronously along the slide rail with the winding and unwinding rhythm of the wire rope. At the same time, the limiting brackets 15, which are staggered on the upper and lower sides of the wire rope retainer 9, further limit the wire rope 7 through the through holes, constraining the swing range of the wire rope 7 from both the upper and lower directions, and preventing the wire rope 7 from deviating due to uneven force, vibration and other factors during the winding and unwinding process, effectively preventing it from derailing from the rope groove of the winch 6.
[0018] When the gate 2 needs to be opened, the control motor 3 runs in the forward direction, and drives the two sets of winches 6 to synchronously wind up the wire rope 7 through the reducer 4 and the transmission shaft 5. The wire rope 7 pulls the connecting rod 16 upward through the fixed connection point with the top connecting rod 16 of the gate 1, thereby driving the gate 1 to slide upward along the gate frame at the bottom of the mounting base 2. During this process, the wire rope fixing device 9 slides synchronously with the winding rhythm of the wire rope, continuously limiting the wire rope 7 to prevent derailment, and ensuring that the gate 1 rises smoothly. When the gate needs to be closed, the control motor 3 reverses, the winch 6 releases the wire rope 7 synchronously, and the gate 1 slides down along the gate frame under its own weight. The connecting rod 16 descends synchronously with the gate 1, driving the wire rope 7 to unfold smoothly. At this time, the driven shaft 8 rotates in the opposite direction with the transmission shaft 5, driving the wire rope fixing device 9 to slide in the opposite direction. The limit frame 15 always restrains the wire rope 7 during the unfolding process to prevent it from derailing, swinging too much, etc., and ensures that the gate 1 descends smoothly to the designated position.
[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
